The most two important factors of the SFP transceiver: Output power (TX power) and receiver sensitivity (RX sensitivity).
The optical TX power is the signal level leaving from that device, which should be within the transmitter power range.
The RX sensitivity is the incoming signal level being received from the far end device and it should fall within the receive power range.
We will compare the GPON/XGPON/XGSPON Optical Modules separately following:
GPON Optical Module
